Homes in Livingston Parish, LA run heat about five months a year, from November through March. The refrigerant circuit runs in heating mode the entire time, pulling heat from outdoor air that can drop cold enough to push the system toward its capacity floor. The reversing valve shifts the refrigerant's direction of travel each time the system cycles, and the heating season is when that valve earns its wear. A contractor on a repair call here opens with the refrigerant charge and valve operation because those are the parts the season loads hardest, and finding a fault there early keeps a bad coil from becoming a failed compressor.
Ductwork in housing built around the turn of the century has had time to develop leaks at joints, gaps at registers, and insulation that no longer holds. Half the homes in Livingston Parish, Louisiana were built in 2002 or earlier (2020-2024 ACS 5-year). A contractor who opens a heat pump and finds it working harder than its specs suggest will look at the distribution side next, because that is where the load explanation often lives. The part count and the labor on the equipment side of a repair are straightforward to price; what the duct runs are doing to the system's demand is what changes the scope.
The Parts of a Heat Pump a Contractor Checks First
The outdoor unit is the piece most homeowners recognize. It sits outside on a pad or bracket and holds the compressor and the condenser coil. Both are common failure points: a compressor that has lost pressure or seized, and a coil that is damaged or blocked, will each stop the system from moving heat into or out of the house.
Inside, the air handler holds the evaporator coil and the blower fan, typically in a utility closet, attic, or basement. The reversing valve, which lives in the outdoor unit, is what lets the system switch between heating and cooling. A failed reversing valve is often the reason a heat pump runs but delivers only one mode.
The drawing shows a general layout of these components, and a licensed contractor determines which parts apply and what needs attention in your specific home.
